Figure 1 shows a compressor running on refrigerant-134a with a constant mass flow rate of 6 kg/s. The fluid enters as saturated vapor at 700 kPa. After its volume has been compressed by 20%, it exits at 1000 kPa. The inlet and outlet diameters of the compressor are 10 cm and 4 cm, respectively. The fluid is pumped to the next component located 120 m above the compressor. It is also recorded that the compressor loses about 264 kJ/s to the surrounding. a) Considering all energy changes, derive the equation for determining the compressor input power from the energy balance equation. b) Calculate the inlet velocity. c) Determine the outlet phase, velocity, and temperature. d) Calculate the compressor input power.
